Kate, the Princess of Wales, made her first public appearance Sunday since she announced she had completed chemotherapy and would return to some public duties.

Kate and her husband, Prince William, were seen Sunday attending church with King Charles III and Queen Camilla near their royal Balmoral estate in Scotland.

Kate, 42, announced on Sept. 9 that she had completed treatment six months after revealing she had an undisclosed type of cancer. Her announcement came six weeks after Buckingham Palace announced that the king was being treated for cancer.
